In this lesson
Prepare for the SAA-C03 exam (AWS Certified Solutions Architect – Associate). In this lesson: Amazon SQS with its visibility timeout, dead-letter queues, and long polling, standard and FIFO queues, publish and subscribe with Amazon SNS, event-driven architectures with Amazon EventBridge, and workflow orchestration with AWS Step Functions. Includes three original practice questions.
Preview the topics
- A consumer needs about two minutes to process each SQS message, and the same messages are often processed twice by different consumers. What should the architect change?
- Each parcel event must reach three teams, notifications, billing, and analytics, and a slow analytics job must never delay notifications. What should the architect use?
- A parcel damage claim needs several steps over up to three weeks: collect photos, wait for an adjuster’s approval, then refund, with retries on failure. What should the architect use?
